Patented July 11, 1939 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to control means for lamps, usable on boats, trucks or other places and having a construction attached to and passing through a floor, roof or deck and operable at a point remote from the lamp.

Among the objects of my invention is to throw a beam of light from an outside lamp in a desired direction by means of an inside control; to move a lamp in either or both vertical and horizontal planes by remote control; to create a construction having perfect equilibrium and complete balance at all positions of the arc through which the lamp is moved; to provide a construction in which at metallic tension members will replace the jerkiness caused by stiff linkage with an easy and constant movement in adjustment; to supply a construction that will have no dead center and one that will not cause the lamp to move to extreme positions; to create a construction that will be easier to manipulate, more accurate to position and sure in the retention of a desired position, and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing a preferred embodiment of my inven tion, yet I wish it understood that the same is susceptible of modication and change without departing from the spirit of my invention.

Referring to the drawing, Fig. 1 is a sectional view of a preferred form of my construction. Fig. 2 is a front View and Fig. 3 is a detailed sectional view thereof.

Referring to the embodiment selected to illustrate my invention, it comprises a lamp I0 having a housing 45, a lens 4I, an electric light bulb 42 connected to an electrical source of supply and a reflector 43.

A bracket II is attached to the lower portion of the housing 4I) by suitable means such as rivets. The bracket II has a saddle I2 adapted to receive the upper end of a square terminal member I3 which is attached to the upper end of the tube I4. The terminal member I3 is pivotally attached to the saddle I2.

The tube I4 continues downwardly through a standard I5 to a lower terminal member I6 which is seated in a recess I'I of a rocker arm I8. The lamp Ill is preferably located out doors or in a room or deck higher than the location of the rocker arm. The standard I5 has a base I9 adapted to be attached to the deck, floor or roof 20, by suitable means such as bolts, screws or nails.

pivot 34.

(Cl. 24U-61.13)

A bushing 2| is suitably attached by screw threads to the upper portion or flange 5|] of the standard I5, and in a recess 22 of the standard I5 is positioned a packing 23 held in compression against bushing 2|, by springs 24. The 5 springs are held by an inward ange 44 of standard I5.

Standard I5 has a downwardly extending flange 25 which extends below floor, deck or roof 20 and is threaded at its lower end to receive a 10 bushing 32.

A handle for the rock arm I8 is preferably provided in the shape of a ball 21 attached thereto by suitable means.

Pvotally attached to the corner 28 of bracket 15 II is the upper end of flat spring 29. The lower end of flat spring 29 is attached to the outer side of nut 30 by suitable means such as screws. Nut 3U surrounds flange 50 and is rotatable. Nut 3|] is prevented by bushing 2| from accidental go disengagement.

Pivotally attached to the rocker I8 at its lower end is a flat spring 3| which extends upwardly to nut 26 and is suitably attached to the outer side of said nut 26. The nut 26 surrounds flange 25 25 and is rotatable. Nut 25 is prevented by bushing 32 from accidental disengagement.

When it is desired to tilt the lamp III upwardly the user moves the ball 2'I in a right downwardly direction, This pushes the tube upwardly so as 30 to move the lamp upwardly on pivot'33 against the resistance exerted by flat spring 23 and on pivot 34 plus the force exerted by at spring 3|. When the user desires to tilt the lamp down-` wardly he moves the'ball 2'I in a left upwardly 35 direction. This pushes the tube downwardly so as to move the lamp downward by the force exerted on pivot 33 by dat spring 29 and against the resistance exerted by the flat spring 3l on 40 A switch 25 is provided on horizontal arm I8 convenient to the reach of the fore nger when the users hand is on th-e handle.

lowei` flat spring pivotally attached on its lower end to the handle and on its upper end to the lower end of the support, so that upon movement of the handle the tube and the flat springs will move the lamp to a desired position, the tension of one fiat spring counteracting the tension of the other ilat spring to provide smooth movement of the lamp and to maintain equilibrium of the lamp in all positions.

2. A device of the class described comprising a support adapted to be attached to a desired surface, a connecting member slidably and rotatably extending through said support, a lamp pivotally attached to one end of said connecting member, a remote control handle pvotally attached to the other end of said connecting member, a iiat metallic tension member pivotally attached adjacent one end to the lamp and adjacent its other end to the support and another tension member pivotally attached adjacent one end to the handle and adjacent on its other end to the support so that upon movement of the handle the connecting member and the tension members Will move the lamp to a desired position, the tension of one tension member counteracting the tension of the other tension member to provide smooth movement of the lamp and to maintain equilibrium of the lamp in all positions.
